President Donald Trump's import taxes are meant to help US manufacturers by making foreign products more expensive, but some companies say the costs are likely to trickle down to American consumers.

Several companies have either already raised their prices or say they plan to as a result of the tariffs.

According to Labor Department estimates, the average cost of washing machines went up by 17% in the past three months.

President Donald Trump's tariffs are leading to higher import costs for US companies, and it's American consumers who are likely to bear the burden.

While the White House has pointed to national security issues as justification for the tariffs, there's also a practical economic component to Trump's duties. The tariffs on foreign imports such as washing machines, steel, and aluminum are designed to make foreign goods more expensive and therefore US manufacturers more appealing.

Since these tariffs have been in place, several US companies including Coca-Cola and Winnebago have said they have been forced to raise prices on the consumer's side. Others are threatening to follow suit.

According to the Labor Department, the average cost of washing machines was up 17% in just the past three months, The Wall Street Journal reported.

Here's a list of some of America's best-known brands who have spoken out about the new tariffs and either raised prices already or say they plan to:

Coca-Cola

Coca-Cola said on July 27 it would be raising the price of its sodas in the middle of the year.

"There is some broad-based push on input costs that have kind of come in and affected ours and many other industries as well," CEO James Quincey told The Wall Street Journal.

Quincey cited steel and aluminum tariffs announced by Trump earlier this year as one of the causes of increased costs, but did not specify how high the price increase would be.

"We've had to go to the market a bit more frequently and a bit more aggressively with some price increases as of late," Michael Happe, CEO of Winnebago Industries, told The Wall Street Journal in July.

Happe did not confirm how high the prices increases were.

The company has also made changes to the design of the RV to trim costs.

Scott Wine, CEO of Polaris, a company that makes motorcycles, quad bikes, and snowmobiles, said in a recent TV news conference after the release of its second-quarter earnings that the company had raised prices on some items impacted by tariffs, such as motorcycles.

"As we and others raise prices, it creates a real risk of inflation to our customers and the economy, which could be more harmful than the tariffs themselves," Wine said, according to the Associated Press.

The company is looking to move production of motorcycles that it sells in Europe from Iowa to Poland to avoid being stung by EU tariffs on US products, The Wall Street Journal reported.

In a call with investors in July, Whirlpool CEO Marc Bitzer said that the rising cost of raw materials that has resulted from US tariffs on steel and aluminum was putting pressure on the company's earnings.

The company said it is looking at price hikes to cover these costs but did not specify by how much.

General Motors

Chevrolet

In June, carmaker General Motors submitted a letter to the US Commerce Department urging the president to abandon the plan for auto tariffs, saying that they would lead to price increases of thousands of dollars, The Financial Times reported.

"At some point, this tariff impact will be felt by customers. Based on historical experience, if cost is passed on to the consumer via higher vehicle prices, demand for new vehicles could be impacted," the letter said.

In January, LG Electronics said it would raise the prices of washing machines by 4-8% in March, Reuters reported.

This works out to about $50 more per machine, a spokesperson for the company told Reuters.

Gavin Hattersley, CEO of MillerCoors, the maker of Coors Lite and Miller Lite, told Bloomberg in June that it may have to look at raising prices on the consumer's side.

"I can't just go to the shareholders and say, 'You're just going to have to accept my profit's going to be $40 million less. It doesn't work that way," he said.

"It's costing the American consumer. It's absolutely not what the president intended, in my view, but it's a consequence of what he did," he added.

In a call with investors on July 26, the company said there could be more price increases in the second half of the year thanks to higher commodity costs.

"This is a very competitive industry and we want to maintain our competitiveness. But we are starting to see, on a local basis, price increases coming through at a time when they wouldn't normally be reflected," James Koch, chairman of the company, said on the call.

During a call with investors in May, CFO Anthony DiSilvestro said that US tariffs on steel and aluminum were likely to put pressure on the company's margins, and it's expecting them to be down in fiscal 2019.

"Obviously, the question is what is the impact of potential pricing to help to offset that," he said, without giving more detail.

Toyota

The Japanese company told Bloomberg in June that the 25% tariff "is just a tax on consumers," adding that it would pass the additional costs on to the consumer, which would lead to an increase in the cost of all of its vehicles sold in the US.

As an example, the Toyota Camry would face $1,800 in increased costs, a spokesperson for the company told Bloomberg.
